On top of keeping your up-time high for all your systems and users, monitoring hardware/software Faults, Availability and Performance issues will be at your finger tips, as many of these programs and tools listed before have intuitive and simple interfaces with built-in reporting and graphs to help you manage everything in a centralized location.

What should you look for in free network monitoring tools?

We reviewed the market for free network monitoring software and analyzed the options based on the following criteria:

  • Capabilities to poll for device statuses with SNMP out of the box
  • The ability to receive and process Trap messages into alerts
  • Live performance graphs in the dashboards
  • A self-installing, easy-to-use package
  • Autodiscovery of network devices that repeats continuously
  • A free trial or demo system that allows a no-risk assessment
  • Good value for money provided by a set of quality tools at a reasonable price

With these selection criteria in mind, we have identified the top network performance monitors that use the Simple Network Management Protocol to communicate with switches and routers. We made sure to include options for both Windows Server and Linux.
